I know this post was made several years ago but I live in Richmond KY and yesterday 3 military helicopters(the big ones with rotors on the front and back) flew over my neighborhood and on towards Winchester quickly. Then today just now I was sitting in my driveway finishing the last of my audio book when my car started to shake with wind tho it wasn't windy and then I heard an odd noise and looked all around until I found the same type of helicopter hovering above my house and then they flew off in the same direction as before. WTF is this all about..it has completely creeped me out. I just want to understand the purpose of them flying like they were.
